Today we had the pleasure of hearing Professor Mike Knodler from the UMass Department of Civil and Environmental Engineering speak in our UMass Amherst INFORMS Speaker Series.

Dr. Knodler in the Director of the UMass Transportation Center, which includes the UMass traffic Safety Research program. We were all very much looking forward to his presentation and it was fascinating and very dynamic!

The morning began with a celebration of the UMass Amherst INFORMS Student Chapter's receipt of the Cum Laude Award from INFORMS at the INFORMS Conference in Phoenix, earlier this month, complete with a cake.

And we took a photo of the officers present.

It was great for the audience to have a chance to mingle with the speaker and one another before the presentation.

Professor Knodler began his presentation with the question: "What is OR (Operations Research)?" and stated that their work in transportation is to get OR into practice. He emphasized the incredible diversity of transportation and that the Center has 100 different funded topics in 60 different areas. The UMass Transportation Center links researchers with practitioners and now even includes an Aviation Center with an air traffic control simulator. Several of those affiliated with the Center are also conducting research on drones.

In his presentation he described some of the innovations to enhance traffic safety from signals to infrastructure design and also emphasized that recently the number of traffic deaths have been increasing in the US. He highlighted the many different modes of transportation introduced fairly recently, from electric bikes and scooters to under development, even hovercraft. He also spoke about complete streets and complete networks.

A highlight was when he brought out a Segway (and then another one was delivered) and brave members in the audience had the opportunity to ride one.

What very much impressed me was how the research done at the Transportation Center has become policy not only in the state of Massachusetts but even nationally.

After the great presentation and exciting Q&A we took a group photo.

Then it was time for lunch at the University Club and continuing conversations. Professor Knodler, though, had a meeting, and had to miss the desserts.

We thank Professor Knodler for taking the time out of his very busy schedule to share with us the exciting contributions of his research group and the UMass Amherst Transportation Center!

For example, on November 6, bright and early, at 7:30AM, I had the pleasure of taking part in a panel under the auspices of the Junior Faculty Interest Group (JFIG) of INFORMS on Advising PhD Students. I was very much looking forward to this panel - to hearing insights from
the other panelists and also the questions from the audience and the
discussions that would take place.

The panel began with my presentation, followed by a presentation by Professor Geunes, and then one by Professor Butenko. My perspective was that of a Business School faculty member (although I have also supervised several dissertations from Engineering at UMass Amherst) and the other panelists provided their perspectives as Engineering faculty. All of us have graduated over a dozen PhD students. My list of 20 PhD students, whose dissertation committees I have chaired, are featured below, thanks to the Mathematical Genealogy project.

In fact, when I was a junior faculty member, I approached Dr. Alexander Rinooy Kan of The Netherlands and asked him what advice would he give me and he told me, as I have stated in the above slide: "build your network and do this by graduating PhD students." I mentioned in my talk that one of the greatest compliments that I have received was from a senior colleague at a top research university who said that most advisors graduate one or two very successful PhD students, and he was very impressed by how successful many of my former doctoral students are. Indeed, I am a very proud academic Mom, and, what thrills me, as well, is how many of my former doctoral students continue to work and publish with one another - even if they did not overlap as students! The camaraderie and esprit de corps I try to nurture through the Virtual Center for Supernetworks.

The panelists described how they supervise/manage their doctoral students and their research, how often they meet with their students, the importance of having students submit papers to journals during their doctoral studies, and even how doctoral students have "changed" over the years. Different panelists noted that they give different degrees of "freedom" to their doctoral students in terms of topic and research directions, with some beginning as "macromanagers" and then moving to "micromanaging." The coursework, major milestone exam requirements, and teaching requirements at business schools versus engineering schools, were also highlighted as well as how to nurture a student's strengths and how to overcome weaknesses. It was clear that the panelists' experiences with their doctoral dissertation advisors influenced how they mentor/supervise their own students now.

Audience questions ranged from how a faculty member learns to keep a professional distance, despite youth, and the order of authors on a publication.

I personally believe - and this I emphasized in my presentation - that doctoral students need to develop/grow their skill sets not only in terms of research expertise but also their teaching and service skills (including leadership skills). As for the development of service skills, I emphasized the opportunities provided by the UMass Amherst INFORMS Student Chapter, whether in hosting speakers, or even organizing social events and field trips. In fact, officer activities often comes up when students are on the academic job market. To be a successful academic who have to be able to perform at a very high level in all areas of research, teaching, and service (with service to a lesser extent early in one's career).

The panelists clearly showed the passion that they have in supervising doctoral students and even emphasized that they consider this to be their most important role as faculty members.

And the panel organizers even presented the panelists with a JFIG mug - many thanks for organizing this interesting panel and also for the thoughtfulness!

I would be standing on the "shoulders of giants" so I wanted to deliver a talk that would be inspiring, from the heart, very informative; one that I would enjoy giving and that the audience would enjoy as well! The title that I selected was: Networks to Save the World: OR in Action. This was an exceptional INFORMS conference for numerous reasons, including the number of female plenary and keynote speakers.

I had worked on my presentation over many weeks, giving it a lot of thought and effort and was very excited for the opportunity to share experiences and insights with operations research and analytics colleagues from around the globe, from students to very senior colleagues.

After a full day of travel on Saturday, I was very "pumped" for my talk at 3:10PM (my body clock said it was 6:10PM). It was extra special to see so many of our UMass Amherst Isenberg School of Management PhD alumni and also College of Engineering alumni showing up early to welcome me in the big ballroom. It was also great to have two of my present doctoral students, Deniz Besik and Pritha Dutta, come with backups of my talk and they also served as photographers.

Professor Tim Anderson gave a very warm introduction and then it was time for my lecture!

I had to acknowledge the work of my dissertation advisor at Brown University, Professor Stella Dafermos, depicted in the above slide. I also included in my talk the awesome academic pedigree that I am part of - thanks to the Mathematics academic genealogy project with the outstanding scientists: Maxwell, going back to Newton, and even Galileo, being part of my academic genealogy.

In my talk, I discussed many application of networks from transportation and the Braess paradox to perishable product supply chains from food to healthcare to disaster relief and even our project on Future Internet Architecture, known as ChoiceNet.

After my presentation, I had many questions, and it was thrilling to have members of the audience come up to chat. I can't thank everyone personally, but I do want to say that I am extremely appreciative. I am also very grateful for the thoughtful gift presented to me after my lecture by Professor Tim Anderson and INFORMS! Special thanks to the INFORMS staff who came to my plenary talk and for their kind comments that they enjoyed it very much.

After the plenary, it was time for an editorial board meeting and then I wrapped up a perfect day by hosting my doctoral students (both past and present) who had made it to the conference by Sunday (others were coming on subsequent days) for dinner.

In the above photo are: Dr. Jose Cruz, Dr. Shivani Shukla, Dr. Min Yu, Dr. Amir Masoumi, Deniz Besik, Pritha Dutta, Dr. Dmytro Matsypura, who traveled all the way from Sydney, Australia, and even brought his doctoral student, Jessica. It was her first INFORMS conference and her first scholarly presentation.

The past, present, and future of OR are a powerful network of scholarship and community! I am so lucky to be part of INFORMS and this fabulous profession.
